Landing maneuvers are critical tasks for unmanned aerial vehicles (UAVs) and need very precise information on the altitude above ground level (AGL). Radar is a suitable technology for this application, because it can not only sense the altitude AGL but also the rate of descent. In addition, obstacles or unsuitable terrain for landing can be detected. With the 122 GHz monostatic radar sensor presented in this paper, high bandwidth can be achieved in order to obtain range resolution in the single digit cm-range. Measurements are performed for different bandwidths to verify the concept.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
